means A liquid mixture, often medicinal or magical, that you drink to produce some intended effect — healing, harm, love, or transformation.

from From Latin 'potio,' meaning 'a drink' or 'draught,' rooted in the verb 'potare,' 'to drink' — the same thirsty source that gives us 'potable' water. It reached English through Old French 'pocion.' Notably, 'potion' and 'poison' are twins separated at birth: both descend from that same Latin 'potio,' which is fitting, since a drink meant to cure and a drink meant to kill are often only a dosage apart.
